Spatial and temporal effects of atmospheric deposition, climate, and land management on forest nutrient cycling and biodiversity

Creator:: McDonnell, Todd C.
Abstract:: Emissions largely associated with the combustion of fossil fuels and agriculture has caused elevated atmospheric deposition of nitrogen (N) and sulfur (S) throughout much of the developed world. Increased atmospheric deposition of N and S can lead to soil and surface water acidification and affect forest soil nutrient supply. The...

Carbon dynamics following landscape fire: influence of burn severity, climate, and stand history in the Metolius Watershed, Oregon

Creator:: Meigs, Garrett W.
Abstract:: Fire is a fundamental disturbance that drives terrestrial and atmospheric carbon dynamics. Previous studies have quantified fire effects on carbon cycling from local to global scales but have focused nearly exclusively on high-severity, stand-replacement fire. Since 2002, variable-severity wildfires have burned more than 65 000 ha across the east slope...

Sensitivity of a subregional scale atmospheric inverse CO₂ modeling framework to boundary conditions

Creator:: Göckede, Mathias, Turner, David P., Michalak, Anna M., Vickers, Dean, and Law, Beverly E.
Abstract:: We present an atmospheric inverse modeling framework to constrain terrestrial biosphere CO₂ exchange processes at subregional scales. The model is operated at very high spatial and temporal resolution, using the state of Oregon in the northwestern United States as the model domain. The modeling framework includes mesoscale atmospheric simulations coupled...

Forest Successional and Disturbance Dynamics in the Southern Blue Mountains of Eastern Oregon

Creator:: Johnston, James D.
Abstract:: The application of modern land management practices beginning at the turn of the 20th century is widely believed to have dramatically transformed forest landscapes of the inland Pacific Northwest. Restoring historical conditions to make forests resilient to future climate and disturbance regimes is a major goal of federal forest managers....

Supplemental Feeder Use by Free-Living Black-capped Chickadees (Poecile atricapillus) in a Mediterranean Climate

Creator:: Lajoie, Janel L.
Abstract:: The majority of households in the U.S., Great Britain, and Australia feed wild birds, and 53 million people in the U.S. spent more than $5 billion on bird food and feeding accessories in 2016. Given the massive scale over which it occurs, purposeful feeding of wild birds has the potential...

Combined Effects of Intensive Forest Management and Microclimate on Reproduction in a Cavity-Nesting Songbird

Creator:: Jones, Kristin N.
Abstract:: Future scenarios of global climate change rely on large-scale climate envelope models that do not account for local climatic conditions to which organisms most closely respond. Shifts in species distributions and phenology driven by climate change are well-documented, yet we lack a strong understanding of how climate change will influence...

A Review and Recommendations for Assessing Floodplain Vegetation Recovery Following Stage 0 and Beaver Dam Analog Restorations in the Pacific Northwest

Creator:: Colley, Lara K. M.
Abstract:: Floodplains are a significant and increasingly threatened ecosystem. As restoration projects are implemented more frequently in degraded floodplains, novel methods are emerging with a focus on restoring critical processes in which vegetation plays a key role. The purpose of this paper is two-fold: 1) to develop expectations for vegetation response,...

Conditions favouring Bromus tectorum dominance of endangered sagebrush steppe ecosystems

Creator:: Reisner, Michael D., Grace, James B., Pyke, David A., and Doescher, Paul S.
Abstract:: 1. Ecosystem invasibility is determined by combinations of environmental variables, invader attributes, disturbance regimes, competitive abilities of resident species and evolutionary history between residents and disturbance regimes. Understanding the relative importance of each factor is critical to limiting future invasions and restoring ecosystems. 2. We investigated factors potentially controlling Bromus...

Satellite Monitoring of Earth’s Surface Temperature : Effects of Land Cover, Disturbance, and a Changing Climate

Creator:: Mildrexler, David J.
Abstract:: The Earth’s surface is experiencing unprecedented change. Humanity’s growing population, expanding land-use footprint, and increasing global emissions of atmospheric greenhouse gases affect a vast number of species on Earth and the functioning of virtually all ecosystems. Given the vital interactions and feedbacks between the Earth’s land surface and climate, measurements...

Historical forest succession and disturbance dynamics in Coastal Douglas-fir forests in the southern western Cascades of Oregon

Creator:: Merschel, Andrew G.
Abstract:: Coastal Douglas-fir (Pseudotsuga menziesii var menziesii) forests are extensive west of the crest of the Cascade Mountains in Oregon and Washington and are renowned for their productivity, biodiversity, and the ecosystem services they provide. Increasing wildfire activity in recent years including the extensive 2020 Labor Day fires, and a warming...
